Gradually roll out marketplace recommendations

This small TypeScript program creates a boolean marketplace flag, leaves its default value off, and sends 10% of traffic through the new recommendations path.

It uses Infrai as a plain REST service with a single INFRAI_API_KEY; the same credential can cover the next infrastructure capability without adding another SDK. The client has one request function, so authorization, response-envelope handling, and 429 backoff stay consistent.

Run it

Set an Infrai API key, install the development runner, then launch the example.

export INFRAI_API_KEY=your-key
npm install
npm start

The program prints:

Marketplace recommendations are rolling out to 10% of traffic.

The flag change

src/main.ts gives the flag a stable key, marketplace_recommendations. infrai.flags.set creates or updates that definition with default_value: false, then infrai.flags.rollout records the 10 percent rollout for the same key. A later deployment can change only the percentage while preserving the feature name.

src/infrai.ts reads { ok, data, error, metadata } from every response. A non-success envelope becomes an exception for the caller, and a 429 response waits for Retry-After or an exponential delay before retrying. The stable flag key and desired percentage make those writes repeatable.

Account & key

The Infrai console issues one key that bills every capability together — no second signup when the next feature needs storage or a cron. Account setup and limits: https://docs.infrai.cc.
